How to connect a monitor to a computer
After purchasing a new computer, a problem arises - how to connect the monitor to the system unit? In fact, this is not difficult, the main thing is that the connectors match. It’s best to see what connector is on the screen and on the unit before purchasing - in this case, the connection will take a couple of minutes. However, even after a seemingly successful connection, the monitor remains black after turning on the PC. What to do in this case? Let's figure it out in order.

What cables are there for connection?
The hole for connecting the cable to the monitor is the largest in the block. In order for the wire to hold well, it is secured using screws that are already provided by the manufacturer.
Modern units and monitors are equipped with the following types of cable connectors:
- VGA is a fairly old connector, but still found in cheap equipment. It can be used to connect even to the oldest models, but the image is almost always of low quality. The VGA port should be used only if there are no other connectors;
- DVI is the best interface; it transmits the most vivid and clear images. If it is in the block and screen, then you need to connect through it;
- HDMI is a standard connector that exists on most connectors; it transmits a good quality picture, supports video format, and transmits 4K image format (but only low frequency).
The cable required to connect to the processor is selected depending on the connector. Of course, it is most convenient to use VGA - wires for such an interface are inexpensive and are sold at any hardware store. As a rule, the required cable comes with the monitor.
Using the selected cable, you need to connect the connectors in the system unit and the monitor. Check that everything is connected securely and tightly. Plug the cable coming from the monitor into the outlet. It is most convenient to use an extension cord (pilot). After this, turn on the computer and the screen - if everything is done correctly, an image will appear on the monitor.

The monitor cable is not always suitable for connecting to the connector of the computer itself. In such a situation, a guide will help. It will also help if a port is simply missing. The conductor has two different sides - one is connected to the hole for the screen in the block, and the other is used to secure the wire of the desired connector. Using cables, the monitor is also connected to the system unit or video card.
After this, you just need to connect the computer and monitor using the selected cable and check their operation.
IMPORTANT! The adapter is inexpensive, the main thing is not to make a mistake with the holes and buy what you need for your wire and equipment.
How to make the connection correctly - instructions
Connecting your PC to the screen is not difficult at all - you can do it in a few steps. In order not to spend a long time looking for connectors, you need to know where the video card is located in the block - that’s where the place for connection will be. So, the step-by-step instructions look like this:
- Find the cable that plugs into the socket and the cable that will connect to the system unit next to the video card;
- Connect the wire to the outlet, check that it works;
- find the hole into which the cable from the computer will be inserted, check whether it matches the cable;
- carefully, without pressing hard, connect the wire to the connector and tighten the screws, check the reliability of the connection;
- turn on the computer and wait for the picture to appear.
IMPORTANT! Many modern system units have several connectors at once; before connecting, you need to see which one fits the cable. The holes on the block indicate what format they are.
Computer and monitor compatibility
It often happens that everything is connected and should work, but the image either does not appear at all or is of very poor quality. What is the problem? The video card that is responsible for displaying the picture is not compatible with the connected screen.
Before purchasing, you need to decide what diagonal the computer can work with. The larger the screen, the greater the load on the video card and the system unit as a whole.
It is important to understand why you are buying a monitor:
- for games - a large high-resolution monitor, this will require a powerful video card;
- for work and surfing the Internet – a simple screen will do, the load on the video card will not be too heavy;
- for drawing - you will need a wide screen with a high-quality picture and a good video card.
When choosing and purchasing, pay attention to the connectors of the video card and monitor - if they do not match, you need to either buy an adapter or choose another model.
IMPORTANT! If the video card is suitable, the cable is selected correctly, but the graphics leave much to be desired, it is worth updating the drivers.
Why the processor can work, but the monitor does not turn on
It also happens that the computer itself works, but the picture does not appear. There are many reasons why this happens:
- The most common one is that the monitor is not turned on (the Power button is not pressed);
- the monitor is not connected to a power outlet or system unit;
- there is a problem with the video card;
- the necessary drivers are not installed;
- there are problems with the motherboard.
If the computer is turned on and the monitor is not working, you first need to check whether the power button is lit. You can press it several times, it is possible that the button is “stuck”. If the Power button does not light up at all, then the problem is in the monitor. What can be done? Try changing the cable or rebooting the screen.
If when you turn on there is no image itself, but the screen changes light (flashes or brightens), then the problem may be in the cable. Adjusting the brightness can help (it happens that the brightness settings are at minimum and the screen appears black). If something is wrong with the computer, a window will appear on the monitor indicating there is no signal.
Be sure to check the cable - it may be bent or poorly connected. Often the screws break and the cable becomes loose. Ideally, completely replace the wire and turn on the equipment again. If after this the problem persists, you should contact a specialist, because the problem is in the operation of the system.
IMPORTANT! During all manipulations, the computer and monitor must be disconnected from the network.
If a new video card or motherboard was installed, it may not be compatible with the screen. To check this, you need to connect the monitor to another computer, or inspect the video card. Most often, if this is the problem, you hear popping noises when you turn it on.
It happens that the processor is broken and this is not why the image is not displayed. At the same time, the computer makes noise as during normal operation.
IMPORTANT! If the fault lies in any part of the system, then only a professional can help. It is he who will be able to identify the problem and, if necessary, replace parts.
Recommendations
Although the connection itself does not require any special skills, some problems may arise during the process. To avoid them, it is worth reading some recommendations.
- select a monitor depending on the work that will be carried out behind it;
- before purchasing equipment, figure out what ports are available and what cable you will need to purchase; you may need to buy an adapter;
- check for drivers;
- buy a reliable extension cord to connect all the equipment into one “pilot”;
- check the compatibility of the video card with the screen;
- insert and secure the cable into the port carefully, do not press hard on the screws;
- After connecting, check the operation of the equipment, adjust the saturation and brightness parameters.
IMPORTANT! As a rule, the operating system automatically installs the necessary drivers when you turn it on for the first time.
If this does not happen, you will have to install them manually. A disk with drivers may come included, otherwise they can be easily found and downloaded on the Internet.
Thus, independently connecting a new monitor to the computer system unit will not take much time and effort. Of course, it is necessary that the ports of both devices match, and the cable is selected correctly. If any problems occur after connecting, you should check the reliability of the cable and connectors, and the compatibility of the individual components of the computer with each other.If you follow all the recommendations and carefully connect the screen and PC via cable, then no problems will arise, and the bright picture on the new monitor will delight the user for a long time.
